Here's some hints when you do this:
EVERY document should have the part number on it, as well as the date generated, the part numbers should all match. Dates generated should be the dates they were made, do not have to match.
EVERY document in your QMS should also have obvious revision control. So PFD,
PFMEA, Control Plan should all be in your revision control system and it should be obvious on the document. Dimensional reports, MSA, etc, don't necessarily have to be.
Any document with values: dimensionals, initial process studies, metallurgy, gage r&r - not only should have the results, but the LIMITS. Do not leave off the specification limits.
All process steps should exactly match. If your wash process is OP40 in the PFD, it needs to be OP40 in the PFMEA, Control plan, etc.
Less known, but still important:
If it's sloppy looking, your customer is more apt to dig into it. Nobody can send me a PPAP submission that I cannot find a problem with, if I want to. If what you send is disorganized and sloppy, I'm going to spend more time poking around in it, which will be more painful for you. Make sure things like your file names are organized and make sense. You should really number them by element number as well. Make sure that if you are printing to a pdf, you don't have stray page breaks, etc. Think of it like a job interview. It really kind of is - it's like a resume saying "I'm ready to make your part." You want a good first impression. That will give me confidence, and I am less likely to dig. And believe me, there is nothing worse than an SQ who starts digging that doesn't know what they are digging for. Depending on the complexity of the part, an SQ spends about 4 hours examining a PPAP. But if it's sloppy, it gets a lot more attention.
